BALlNG-PRESS.

SPECIFICATION forming part of Letters Patent No. 515,748, dated March 6, 1894.

Application filed May 12, 1898. Serial 170,474,037. (No model.)

To all whom it may concern:

Be it known that we, Has. CLARK, of Kansas City, Wyandotte county, Kansas, and PETER DE LONG MYERS, of Kansas City, Jackson county, Missouri, have invented certain new and useful Improvements in Baling-Presses, of which the following is a full, clear, and exact description, reference being had to the aceompanying drawings, forming a part hereof.

Our invention relates to improvements in bailing-presses; and the objects of our invention are to produce a power for driving or forcing the pitman to compress the hay in the baling-case, which exerts a, positive, steady and continuous pressure from the beginning to the end of the stroke; to produce means whereby said power is opposed by the minimum amount of frictional resistance, and also to provide a means to guide the pitman in its stroke and hold it against the pressu re-power.

A further object of our invention is to provide means whereby, as the power-arm passes from engagement withthe pitman at the end of its stroke, the pitman is induced positively to return to its former-position at the proper side of the power-arm, and also to produce means whereby the pitman is guided and limited in its return movement or recoil, so as to prevent the pounding and shock or jar incident to the recoil of the pitman. Furthermore to produce abaling-press, which is simple, strong, durable and inexpensive of construction.

With these objects in view, our invention consists in certain peculiar and novel features of construction and arrangement of parts, as will be hereinafter described and pointed out in the claims.

In order that our invention may be fully understood, we will proceed to describe it with reference to the accompanying drawings, in which Figure l,is a top-plan view of a baling-press constructed in accordance with out-invention, and showing the pitman at the beginning of its stroke. Fig. 2, is a side elevation of the same. Fig. 3, is a top plan view of a portion of the baling press, and showing the position of the pitman after two-thirds of its stroke has been made. Fig. i, is a similar'view, but showing the piiman at the end of its stroke.

Fig. 5, is a vertical section taken on the line 5-5 of Fig. 1, and looking toward the front end of the machine. Fig. 6, is a vertical section taken on theline 6-6 of Fig.1, to more clearly show thearrangement ofthe guide and clamping-plates. Fig. 7, is a perspective view of the guide and clamping-plates detached from the guide or track-rails. Fig. 8, is adetached perspective view of the bracket, and the pushspriug carried thereby. Fig. 9, is a detail perspective view of the power-shaft, its component parts and the sweep carried thereby. Fig. 10, is a detail perspective view of the plunger.

In the drawings, 1 designates the bed-plate of a baling-press; this bed-plate being of any suitable or preferred material, and formed with a yoke 2 at its forward end. The bedplate is supported at its rear end in the usual manner, and is supported upon and pivotally connected to the front axle 3, by the king-bolt 4, the opposite ends of the axle having the wheels 5 mounted thereon in the usual manner.

Secured upon the bed plate a suitable distance from its rear end is a baling-case 6, with which communicates and extends up wardly therefrom the feed hopper 7. Secured transversely and horizontally to the under side of the bed plate a suitable distance forward of the front axle is a bar 8. The power shaft 9 is vertically mounted and supported in the usual manner through the yoke portion of the bed plate and is formed a suitable distance from its upper end with the enlargement 10, which bears against the under side of the upper or rear end of the yoke portion of the bed-plate. Formed integral with the power shaft and projecting outwardly therefrom and oppositely to each other are the power-arms 11; these arms being formed with the bifurcations 12 in their outer ends in which are revolubly mounted the anti-friction rollers 13. Formed integral with the upper end of the power shaft is the cross-arm 14, which is provided with a socket 15 upon one end, in which is secured the inner. end of the sweep 16 by bolts 17 which pass through the cross-arm 14. A brace-rod 18 adapted to be bolted or otherwise suitably connected to the outer end of the sweep arm in the usual manner, has its inner end passed through an opening in the cross-arm l4, and is engaged by retaining nuts 19 which bear against the opposite sides of the said cross-arm 14. An arch-bar 20 has its lower or free ends bolted at 21 to the upwardly extending ears or projections 8 of the transverse bars 8, and is formed at its central portion with a vertical and semi-cylindrical recess 22 adapted to fit snugly against that portion of the power shaft 9 between the upper side of the yoke 2 of the bed plate, and the under side of the crossarm 14. A bearing cap 23 is fitted against the opposite side of said shaft and is secured by bolts and nuts 24 and 25 respectively, to the arch-bar ,thusforming an additional brace and bearing for the upper end of the power shaft. To form an additional brace for the powershaft and also to form a longitudinal brace for the baling-case, a tie-rod 26 is provided;

this tie-rod being secured at its forward end to the bearing cap 23, and has its rear end passing through the semi-circular coupling brace 27, bolted at its opposite ends or otherwise suitably secured to the opposite sides of the baling-case. Secured at their forward ends upon bolts 28 to the vertical portion of the yoke 2 of the bed plate, is a pair of horizontal and parallel guide or track rails 29 5 these guide or track rails being formed preferably of angleiron. The forward portions of these guide or track rails are arranged concentrically to the axis of the power shaft for a suitable distance at or, they then extend rearwardly and parallel with thebed plateadistanceequal totheradius of the forward curved portion at y, and then their rear end or portion is curved inwardly at z to the sameradius as the front curved portion and concentric to a point rearward of the axis of the power shaft, equal to the length of the radius of said curved portion. The rear ends of the guide or track rails are then carried transversely of and above the bedplate, and are secured to the horizontal arms 30, of a bracket 31, which is bolted or otherwise suitably secured at 32 to the bed plate. Riveted or otherwise suitably secured to the bracket 31 and projecting toward the forward end of the machine preferably is a push spring 33; the object of which will be hereinafter referred to. The guide or track rails are also additionallysupported by the hanger 29, secured at its opposite ends to the upper rail and to the arch-bar 20, and by the standard=29", secured at its opposite ends to the lower rail and to the transverse bar 8.

The parallel guide or track rails are arranged opposite the upper and lower sides respectively of the horizontal power arms 11 of the power shaft 9, and the pitman 34 is adapted to operate horizontally between said guide or track rails, and in the same horizontal plane as the power arms. The forward end of the pitman, which may be of wood as usually constructed, or of metal if preferred, is provided atits upper and lower sides with anti-friction rollers 35, journaled upon the upper and lower ends of the vertical bolt or pin 36; said rollers being arranged to project slightly beyond the outer edge or margin of the pitman, and adapted to travel along the upper and lower guide or track rails as the pitlnan is forced rearwardly to compress the hay in the baling case. The inner edge or side of the pitman is also formed with an outwardly inclined or beveled surface Cb, com mencing a slight distance inward or rearward of the anti-friction rollers, and extending forwardly to meet the rear end of beveled edge I), which is arranged ata greater angle than the bevel a, and extends forwardly or outwardly to the front end of the pitman. The front end of the pitman is rounded at its inner corner and at its outer corner is formed with a projection c, the object of which will be hereinafter described. Secured to the lower and the upper sides of the top and bottom guide or track-rails 29 at their forward ends and adjacent tothe front end of the yoke, by-

bolts, rivets, or other suitable means are the spring-guide and clamping plates 37, the inner or rear ends of which, respectively incline upwardly and downwardly to form a flaring openingor mouth therebetween, and the outer ends project outwardly and forwardly a suitable distance from the guide or track rails, and are provided respectively, with the upwardly and downwardly projecting pins or lugs 38. A spring clip 39, approximately U- shape in side view, has its free end formed with openings which engage the pins 38 at the upper and lower sides of the outer ends of the spring guide and clamping plates 37, and a bolt 40 is passed vertically through said spring and has its upwardly projecting screw threaded end engaged by a clamping nut 41. From this construction it will be seen that by operating the nut upon the bolt 40 this clip may be made to increase or decrease the pressure upon the clamping or outer ends of the spring guide and clamping plates 37, the object of which will be explained in the operation of the, machine.

The rear end of the pitman is pivotally mounted to operate laterally upon the vertical bolt 42, in the flaring mouth or socket 43 of the plunger 44 adapted to reciprocate within the baling case 6. This plunger is mounted upon rollers 45 journaled at the sides thereof, and is also provided with horizontally arranged rollers 46, there being two of these rollers 46 at each side of the plunger and arranged in vertical alignment with each other. The object of these horizontal rollers 46 is to reduce to the minimum, the friction between the sides of the plunger and the sides of the baling-case during the reciprocation of the plunger therein. A retracting spring 47 is also secured at its front end to a bolt or projection 48 secured to the bed plate,and has its rear end secured to a belt or projection 49 secured to the pitman adjacent to the plunger. It is designed by this construction to obtain the greatest movement of the stroke with a minimum expenditure of power, and:

IIO

to obtain this result the first ninety degrees of movement of the power shaft is designed to force the pitman to travel two-thirds of the entire length of the stroke, While the last half of the revoluble movement of the powershaft, (having the pressure) is designed to move the piston the remaining one-third of the stroke and compress the hay tightly in the bailing-press.

In the operation of-the device, the power being applied, the friction roller 13 of one of the power arms 11 bearing against the bevel surface or edge a, of the pitman forces said pitman outwardly and rearwardly, and causes the rollers to travel along the guide or track rails 29 5 the roller 13 next comes in contact with the beveled edge or face 1), the greater bevel or inclination of which face, allows the roller to have a square bearing thereon or greater purchase, and forces the pitman to continue its rear and outward movement unspring 33.

til the roller 13 bears against the end of said pitinan, and the anti-friction rollers 35 have reached the rear end of the straight portion y, of the guide or track rails, and the pitmau has completed two-thirds of its stroke. The continued movement of the shaft, now causes the roller 13 to bear. inwardly and directly upon the end of the pitman until the end of the stroke of the pitman .has been reached, and the free end of the pitinan has assumed the position shown in Fig. 4, and the beveled surface a thereof, is in contact with'the push- The continued revoluble movement of the power shaft in the direction of the arrow, forces the pitman against the pushspring until the roller 13 has cleared or moved from contact with the end of said pitman; the push-spring, and alsothe projection c, uponthe endof the pitm an, resisting any further movement of the pit-man in that direction. As soon as the roller 13 of the power-arm 11, has cleared entirely the free end of the pitman, the retracting spring 47 and the expansion of the hay, cause the pitman to move forward and resnmeits former orinitial position; the pushspring 33 by pressing against the bevel edge a, of the free end of said pitman, havinga tendency to force it toward the proper side of the power-shaft. The expansion of the hay and theretracting power of the spring 46 causes the pitman to move forward with terrific force, andto prevent the usual pounding and jar or shock to the machine which is incident to this return movement of the pitman in all haypress machines of this character, the spring clamping and guide plates are provided; the

forward or free end of the pitman being guided in the flaring opening formed between said guide-plates and coming in contact with the clamping end of said plates, which frictionally engaging upon the upper and lower sides of the end of the pitman, is gradually arrested, so that by the time the pitman has reached its initial position as shown in Fig. 1 there will no pounding or shockresuit; the spring clip being arranged to the proper tension.

The clamping arrangement of the spring guide andclamping plates at the front end of the guide or track rails and adjacent to the yoke of the bed plate is so arranged, that the anti-friction rollers 35 carried at the upper and lower sides of the pitman will not strike thereagainst, upon the return movement of the pitman.

From the above description, it will be seen that we have produced a baling press, in which the pressure upon the pitman is steady, positive and continuous from the beginning to the end of the stroke, and in which the greatest length of stroke is obtained with the minimum amount of power expended,.and in which said power is opposed by the minimum amount of frictional resistance. Also it will be seen, that we have provided a means to guide the pitman in its stroke and hold it against the pressure power, and furthermore a means whereby, as the power arm passes from engagement with the pitman at the end of its stroke, the pitman is induced positively, to return to its former position at the proper side of the power shaft; also means, whereby the ICC intermediate longitudinally extending portion connecting the front and rear portions, and a pitman, interposed between the guide or track-rails, and having anti-friction rollers a suitable distance from its front end, which bear againt the inner edge or side of the guide or trackrails, of a power-shaft also carried by the bed-plate, and arranged concentric and eccentric respectively, to the front and rear curved portions of the guide or track-rails,

and having power-arms which in operation gradually transfer their leverage from a point inward of the end, along the inner-side or edge to and against the free end of the pitman, to cause the friction rollers thereof to follow the guide or track rails, substantially as set forth.

2. In a baling press, having a bed-plate,
